PURPOSE:The titled composition giving a molded product excellent in environmental stress-crack resistance without detriment to impact strength or heat resistance, which is prepd. by compounding a polycarbonate resin with PE and an isoprene rubber and/or methylpentene polymer. CONSTITUTION:A composition prepd. by compounding 100pts.wt. polycarbonate resin (A) with 0.3-20pts.wt. PE (B) and 0.3-20pts.wt. isoprene rubber and/or methylpentene polymer (C). It is possible to obtain a polycarbonate resin composition with improved solvent resistance and enhanced lubricating property, giving molded product having excellent environmental stress-crack resistance but no residual stress without detriment to good characteristics such as impact strength and heat resistance, by mixing the component A with a combination of the components B and C in a specified proportion. |
